a boat that gets bored of water and decides to fly above it
means A wing-like fin mounted beneath a boat that, at speed, lifts the hull clear of the water to reduce drag — or the fast vessel equipped with such fins.
from A 20th-century compound stitched from two Greek-rooted parts: 'hydro-', from Greek 'hydōr', water, and 'foil', which traces back through Old French 'fueille' to Latin 'folium', a leaf — the same 'foil' used in aviation's 'airfoil'. So the word literally means a 'water-leaf' or water-wing, a sibling to the aircraft wing it shamelessly imitates.
